AUTOMATIC TAKE-UP FOR ROTARY KNITTING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 463,788, dated November24, 1891.

Application filed June 17, 1891.

To aZZ whom it may concern:

Be it known that we, \VALLAUE HOSE and HENRY CURTIN, of Little Falls, inthe county of IIerkimer, in the State of New York, have invented new anduseful Improvements in Automatic Take-Ups for Rotary Knitting-Machines,of which the following, taken in con nection with the accompanyingdrawings, is a full, clear, and exact description.

The purpose of this invention is automatically to take up and windneatly and compactly upon a roller the fabric issuing from theneedle-cylinder of a rotary knitting-machine and to effect the same at acontinuous and uniform speed corresponding to the speed of knitting; andto that end the invention consists in the novel take-up mechanismhereinafter fully described, and set forth in the claims.

In the annexed drawings, Figure 1 is a side elevation of aknitting-machine embodying our invention, a portion of the frame beingbroken away to illustrate more important tal gear-wheel, which isattached to and drives the needle-cylinder. Fig. 4 is a horizontaltransverse section on line y y, Fig. 1. Fig. 5 is an inverted plan view,partly broken away, of the lower end of the revoluble frame, showing theadjustable attachment of the pinions which transmit motion from thestationary gear to one of the take-up rollers. Fig. 6 is a top view ofthe aforesaid attachment of the pinions. Fig. 7 is an enlarged verticaltransverse section of the main portions of the revolubletake-up-carrying frame, taken on line 2 .2, Fig. 8; and Fig. 8 is anenlarged vertical sectional view on line 0 0, Fig. 7.

Similar letters of reference indicate corresponding parts.

Serial No. 396,564. (No model.)

passes down through the tubular hubs of the needle-cylinder and of thewheel B, as indicated by dotted lines 1 1. In order automatically totake up this fabric issuing from the needle-cylinder at a uniform speedcorresponding to that of the knitting, we employ the followingmechanism.

To the under side of the gear-wheel B we rigidly secure the verticalframe 0, the lower end of which is sustained laterally by a horizontalspider F, rigidly secured to the lower portion of the frame F and havingfirmly and rigidly secured to it the spur-wheel I-I, upon the hub ofwhichthe base of the frame 0 v rides and is pivotally secured to it by abolt n, passing vertically through the spider and the aforesaidsuperimposed parts, as best seen in Fig.2 of the drawings.

R denotes the take-up roller upon which the fabric is to-be wound, saidroller extending horizontally across the frame and is sup ported toyield vertically, preferably byvmeans of prolonged spiral springs cseated in vertical tubes d d, secured to opposite sides of the frame,said tubes being slotted vertically at their upper ends for thereception of the trunnions of the roller B, said trunnions being mountedin journal-boxes e, which are mounted upon the upper ends of the spiralsprings d. The vertical slots areextended through the upper ends of thetubes to allow the roller to be removed when desired.

In order to allow the aforesaid springs to be adjusted in their tension,we close the lower ends of the tubes d dand provide the bottoms of thetubes with screw-threaded eyes, in which are inserted set-screws e e,upon the inner ends of which rest the followers (1, on which the spiralsprings are mounted, as shown in Fig. 7 of the drawings.

R represents an auxiliary take-up roller, which is arranged before thetake-up roller proper R and parallel therewith and preferably fluted.Said auxiliary roller is j ournaled at opposite ends-in the frame 0, andhas one end of its shaft projecting from the exterior of the frame 0,and has loosely mounted on it a worm-pinion f, and to the outer side ofthis pinion is fastened one of platesj of the friction-clutch. The otherplate j of said clutch is mounted to move longitudinally on the shaft,and is connected to it by spline and groove, as shown at j in Fig. 7 ofthe drawings, and has secured to the side adjacent to the platejafriction-disk 7c, of leather or other suitable material. The free endof the shaft of the roller R is screw-threaded and provided with aset-nut m and jam-nut m, and between the nut m and clutch-plate j isinterposed a spring-plate o, as clearly shown in Fig. 7 of the drawings.2y turning the nut on so as to cause the spring 0 to press theclutch-plate j tightly against the other clutch-plate j, the worm-pinionf be comes fastened to the shaft of the roller. Said pinion receivesrotary motion from the worm g on the upper end of a vertical shaft g,which is journaled in suitable bearings secured to the rotary frame (J.

To the base of the frame 0 is fixed a horizontal arm 0, which projectsfrom the side of the aforesaid frame, and has pivoted in i s free end ashort vertical shaft projecting from the top and bottom of the arm andhaving secured to opposite ends thereof two pinions i i. The lowerpinion t' meshes with the spur wheel H and the upper pinion t" mesheswith the pinion 72 secured to the lower end of the shaft g.

Inasmuch as coarse-knitted fabric is produced faster than finely-knittedfabric, it is necessary to adjust the gearing so as to conform themotion of the take-up mechanism to the speed of the knitting, and toaccomplish this we employ on the arm G interchangeable pinions t' and L.of different diameters, and in order to allow the said pinions to meshwith the spur-gear H and pinion h we connect the arm 0' to the rotaryframe 0, so as to be adjustable longitudinally, by providing the saidarm with a longitudinal slot 1), through which pass the screws 19',which fasten said arm to the frame C, as shown in Fig. 5 of thedrawings, and upon the said arm we mount adjustably in a similar mannerthe plate 7', in which is stepped at t the vertical shaft g, as shown inFig. 6 of the drawings.

Over the auxiliary take-up roller R and parallel therewith is acompanion auxiliary takeup roller R, also preferably fluted, and heldyieldingly contiguous to the roller R by the journal-boxes b of theroller R, seated movably in guideways a, formed on opposite sides of theframe 0. In line wlth each of said guideways is a chamber a, separatedfrom the guideway by a partition a, which is perforated at its center,as shown in Fig. 8 of the drawings. The journal-box b is provided with astem Z), which projects through the perforation of the partition a" andlongitudinally through the chamber a, and is screw-threaded on its freeend, and to said end is connected an adjusting-nut c, and between theinner end of this nut and the partition ct is a spiral spring 0,surrounding the stem I) and exerting an outward pressure on the nut c,and thereby drawing the roller R toward the roller R.

In the operation of the machine the fabric passes between the tworollers R and R, and after the lower end of the fabric has been oncewrapped around the roller R the top portion of the wound-up fabric ispressed against the fluted roller R by the action of the springs forcingthe roller R upward. or toward the roller R. The*frame O, rotatingsynchronously with the needle-cylinder A and with the fabric issuingtherefrom, maintains the take-up rollers R, R, and R" constantly inproper positions in relation to the needle-cylinder and the travel ofthe fabric from said cylinder. The roller R receives rotary motion fromthe spur-gear II by means of the vertical shaft g and its gearedconnections with the said spur-wheel and shaft of the roller R, ashereinbefore described. The pressure of the roller R upon the fabricpassing between it and each of the othertwo rollers R and R impartsrotary motion to the latter rollers, and thereby passes the fabric tothe take-u p roller R and winds it upon the same.

In the operation of first applying the fabric to the roller R the nuts mm are to be loosened to relieve the clutch member j from the pressure ofthe memberj',the pinion f being I then permitted to rotate freely on theshaft of the roller R, and the said roller can be turned by hand withoutturning the shaft g.

To facilitate the turning of said roller by hand, a hand-wheel t isattached to the opposite end of said roller, as shown in Fig. l of thedrawings. After the fabric has been wound once around the roller R thenuts m m are to be tightened on the shaft of the roller R, so as to lockthe pinion f on the shaft by the clutch j and j. The rollers R, R, and Rare then turned with the motion of the needlecylinder, and the fabric iswound automatically on the roller R.

Having described our invention, what we claim as new, and desire tosecure by Letters Patent, is-- 1. In combination with theneedle-cylinder, the frame G, rotating with said cylinder and providedwith guideways a a, chambers a c, and perforated partitions a betweenthem, the auxiliary take-up roller R, pivoted in said frame beneath saidguideways, journal-boxes b, seated in the guideways, the roller R, jour'naled in said boxes, stems 1), extending from the boxes through thepartitions a" and chambers a and screw-threaded on the free ends, adjusting-nuts c on said stems, and springs 0' between said nuts andpartitions and yieldingly forcing the roller R toward the roller R,substantially as described and shown.
